Last Sentinel arrived at The Game Awards in 2023 with a cinematic trailer and an ambitious promise: a science-fiction open-world action game shaped by former Rockstar Games developers. It has now been three years since that reveal, and gameplay has never been shown publicly. Bloomberg reports that Tencent has decided not to proceed with the project in its current form after a recent development review. The game had been positioned as a potential Grand Theft Auto rival, but now appears unlikely to reach release.
This was a major production rather than a small experimental project. Tencent-backed Lightspeed LA had reportedly been working on it for six years, with development costs reaching hundreds of millions of dollars. A playtest earlier in 2026 is said to have performed poorly, prompting the studio to receive one final opportunity to raise the game’s quality.
The resulting review reportedly took place earlier this week. Tencent is said to have rejected the project, a decision linked to the previously reported loss of 80 positions at Lightspeed LA. The situation highlights how quickly a high-profile concept can lose momentum when its development schedule, costs and creative goals move out of alignment.
Reports point to several possible causes. The project allegedly lacked a consistent direction, a settled creative vision and effective management. Its leader, Steve Martin, had spent 14 years at Rockstar Games and previously ran that company’s San Diego office. Even with experienced leadership, creating a polished cyberpunk open world on the scale associated with GTA was an enormous challenge for a new studio with only a few hundred employees.
Development was reportedly affected by missed deadlines and escalating budgets. Tencent’s decision also comes as the company reassesses its commitment to large-scale AAA game production. For readers who follow the wider arcade and gaming industry, the story is another reminder that a striking reveal trailer is only the beginning of a long and risky production process.
A company spokesperson said Lightspeed LA remains open and continues to make games, while indicating that some version of Last Sentinel may still be in development.
The project’s uncertain future follows other Tencent-backed studio closures. TiMi Montreal was shut after years of funding without releasing a game, while the company’s Los Angeles-based Team Kaiju attracted former Halo and Battlefield leads before it ended up shutting down back in 2023.
Several games launched or incubated during the pandemic-era surge in investment have since vanished or suffered difficult releases. MindsEye, another project promoted as a possible competitor to GTA, became 2025’s worst-rated game and faced allegations that it had spied on employees.
For arcade fans, the lesson is familiar: durable appeal comes from a focused experience, reliable execution and hardware that delivers on its promise. Those weighing a dedicated arcade machine can also consult RETROCADE’s arcade machine buying guide before choosing a cabinet.
